| 摘 要： | 采用两步法配制了Cu-H2O、Co-H2O、MWCNT-H2O三种纳米流体,利用紫外-可见-近红外分光光度计结合积分球原理测试了不同粒径、不同质量分数、不同光程的上述纳米流体在太阳能全波段(250nmλ2500nm)的透射率。结果表明,三种纳米流体的透射率都要比水的小,并且纳米流体的透射率随着粒径的增大以及质量分数的增加而降低,随着光程的减小而增大。在相同质量分数条件下,MWCNT-H2O透射率最小,在250~775nm波段,Co-H2O的透射率要高于Cu-H2O的,而在775~1370nm波段,Co-H2O的透射率要低于Cu-H2O的,表明不同粒子在不同波段具有不同的光吸收性能。
